3rd one I have purchased. started with a plastic one love it. got the concrete stainless one about 12 months ago for travelling for work. now got wife this one because it's close to Rose gold colour and she loves it. so easy to clean and smell free. big fan Cheers team. FYI Rose Gold would be a great colour for female demographic.
Reasons why I purchased this product. Stainless and doesn't have a wire ball inside. There are no corners so cleaning is a breeze. If you are serious trainer and regularly use your current shaker, this is a sound investment.
Quite happy with mine although I have to measure out or guess how much fluid I put in as there’s no gauge on the tumbler wall
